SMOKERS PIPE w David Homer Hayden, Sarasota, Fla., assignor to- ElinorH. Mayer and Dorothy H. Herald,

of Sarasota, Fla.

both 1 Application October 6, 1945, Serial No. 620,796 4 Claims. (01.131-197) The main object of my invention is to provide a pipe which willreduce the temperature of the smoke to a degree that will not supportnicotine and of a construction that will attract and absorb the sludgeand any liquefied nicotine before it reaches the stem of the pipe.

Another object of my invention is to provide a pipe which will give aclean, cool smoke. To effect these results, I provide a constructionwhich includes of course a main outer body bowl and a combustion bowl;The latter is removable and between the two is an intermediate bowl withcirculation passages inside and outside of it. In the bottom of the bodybowl is a chamber through which the smoke and air are drawn and in whichthe volatile substances which have not been deposited before reachingthis point are condensed and the moisture and sludge collected and fromwhich they may be readily removed.

Fig. l is a vertical sectional view of a pipe embodying my invention.

Fig. 2 is a transverse sectional view on the plane of the line 2-2 ofFig. 1.

Fig. 3 is an exploded side view showing the parts of the pipe.

Fig. 4 is a vertical sectional view of a somewhat modified form ofintermediate bowl.

Fig. 5 is a plan view of one half of the bowl of Fig.4. The pipe has amain body or bowl 5 with a stem 6, a combustion receptacle or bowl 1, anintermediate floating bowl 8, agasket 9 and a condensation chamberconsisting of a metallic sump i B and a metallic disc I l. The body hasan outlet opening or passage 6 extending through the stem and the sumpI0 is removably mounted in an opening ill in the bottom of the bowl.

The main body 5 may be made of any suitable hard insulating materialsuch as wood or plastic.

The combustion receptacle 1 is of hard, absorbent but fireproof materialsuch as clay or casein. The gasket 9 may be of any suitable resilientmaterial so that the part 1 can be tightly held in place in the body 5.

The intermediate bowl 8 is formed of molded porous cellular absorbentfireproof material, such as a fibrous moldingsubstance acting as abinder for granulated easily combustible carbon and has ribs l2 on theinside and ribs I3 on the outside so as to leave passages I 2 and I3inside and outside for the circulation of air and smoke from the outletsIt in the bottom of the bowl over the top at I5 to the outlet l6. Theintermediate bowl is in loose relation to the other parts, the ribsmerely holding it in loose offset relatiOh and giving added absorbentand cooling surface for smoke contact. Shoulders [1 are provided aroundthe lower part of the spacer chamber to hold it offset a predetermineddistance from the bowl 1. a

Figs. 4 and 5 show an alternative form of removable bowl 8. serrationsare formed in the upper edge adjacent the gasket to form passages 8"beneath the gasket. The chamber i8. between the metal disc I I an themetal pocket or sump It) serves to collect the condensation of moistureand-the sludge from the tobacco. The'smoke is cooled so that little ifany of the volatile substance, such as nicotine is carriedover into-thestem. By extending the outlet tube It into this chamber l8 no liquid orsludge is likely to get into the stem. So-much liquid is collected inthe sump that it is desirable to empty it after each smoke. It is alsodesirable to remove the deposit of sludge from the sump ID at leasttwice during the life of each intermediate bowl 8. The bowl 3 attractsso much nicotine carrying sludge that after its cellular voids becomefilled all of the smoke passages become choked and when it is removed itresembles a solid body of saturated tarred felt and adheres solidly tothelwalls of the innerbowl'l. Such a condition results from the smokingof about onehalf pound of tobacco, or from one hundred and fifty to twohundred smokes depending upon how tightly the tobacco is packedin thebowl 1. The refill unit consists of the bowls I and 8 and the gasket 9and when saturated can be removed by pressure against the disc I l. Theremoval in that manner can only be done while the pipe is warm,otherwise it is necessary to break the bowl 1 and cut out the bowl 8.

This metallic disc H reinforces the bottom of the bowl 8 and when thesump I0 is removed, the bowls 8 and I may be ejected by pressure exertedthrough the sump opening.

Changes may be made in the details set forth without departure from thescope of the invention as defined in the appended claims.

I claim:

1. A tobacco smoking pipe comprising an outer bowl of hard insulatingmaterial, said bowl having a bottom opening leading to the bore thereof,a second bowl nested in said outer bowl and having a bottom surface.said second-named bowl being of cellular absorbent fireproof material,another bowl of hard absorbent fireproof material nested within saidcellular bowl, a stem on the outer bowl having an axial passagecommunicating with the bore and bottom opening of the outer bowl, aremovable sump in said bottom opening and metallic disc located on thebottom surface of the second-named bowl for reinforcing said bottomwhereby said second and third-named bowls as a unit may be forcedoutwardly through the top of the bore of the outer bowl by pressureexerted upon said disc through the bottom opening when the sump isremoved.

2. A tobacco smoking pipe comprising an outer bowl of hard insulatingmaterial with an opening in the bottom end thereof, a stem formedintegrally with said bowl and having a passage communicating with thebore thereof, a bowl of porous cellular absorbent fireproof materialnested in said outer bowl, ribs on the outer and inner surfaces of saidcellular bowl, shoulders on the lower inner surface of said cellularbowl, the ribs on the outer surface engaging the surface of the bore ofthe outer bowl to provide smoke passages therebetween, another bowl of'hard absorbent fireproof material nested within said cellular bowl andseated on said shoulders and engagin said inner ribs :to provide smokepassages between said second and third-named bowls, said third-namedbowl extending above said other bowls to provide a space therebetween, agasket in said space for holding the bowls together in fixed relation, ametal disc located on the lower outerrsurface of said cellular bowl,aremovable sumpinathe open- :ing in the bottom of the outer bowl and atube in the passage in the stem extending .into the opening in thebottom of the outer bowl and above-the sump.

3. A pipe for smoking tobacco comprising an outer bowl having a smokepassage and a "bot- "tomopening, a removable sump in said bottom openingfor collecting sludge, a tobacco holding :bowl removablysupported in theouter bowl, and a porous, cellular "fire proof absorbent bowlinterposed'between the inner bowl and the outer bowl with smoke passages:between the inner bowl and the cellular absorbent bowl and "between thecellular absorbent bowl and the outer bowl and having a metallic disc-atits lower end above said sump.

4. A tobacco smoking pipe comprising an outer 4 bowl of hard insulatingmaterial having an open ing in its bottom end leading to the borethereof, a removable plug in said opening, a stem formed integrally withsaid bowl and having a smoke passage communicating with the opening insaid bowl, a second bowl removably nested in spaced relationship in saidouter bowl and having an imperforate bottom surface, said secondnamedbowl being of molded porous cellular absorbent fire-proof material, athird bowl removably nested in spaced relationship in said second-namedbowl and having its lower end formed with perforations communicatingwith the spaces between the bowls for passage of smoke, said thirdenamedbowl being of hard, fireproof material, and'a metallic disc covering thebottom of the second named bowl and being engageable by a tool throughthe opening in the bottom end of the outer bowl when the plug is removedwhereby the nested bowls may be forced upwardly out of the outer bowlwithout damage.
